None of my 2e games have gone past turn 4 before it became obvious who would win, and most of those were becoming pretty lopsided by the end of turn 3.
All of the games have been "classic" match-ups (Early EA vs. Minbari, Centauri vs. Narn); Minbari have an edge over the apes 4-2, while the Fanheads have been dominating the Spotheads 5-0.
I give most of the credit for the Centauri wins to the Sulust and Demos. The Sulust feels about right for a Raid ship, but the Demos is over-the-top for Skirmish. Give it two more twin arrays, 10 more structure and bump it to Raid, or drop 2 twin arrays and 2 torps, and keep it at Skirmish*.
*or make a proper point system for the game already!
